So I was browsing the wiki, looking at a couple of edits to make sure that there were no trolls lurking around, when I noticed an abnormally large number of category links at the bottom of the page. Here are a few examples of categories we really don't need in my opinion.
I mean, come on. Only one link in that category? Not really needed, more of a waste of space in my opinon.
And look at the bottom of this page and look at all the categories it has!
For a simple door! All it does is open at the push of a button!
Now, I may be overracting, so if you disagree, please tell me why in the comments below. I personally feel we don't need that many categories.
